retinal detachment

Retinal detachment is a condition where the retina pulls away from the tissue underneath it. It may start in a small area, but without quick treatment, it can spread across the entire retina, leading to serious vision loss and possibly blindness. Retinal detachment is a medical emergency that requires surgery.

The retina is a thin layer at the back of the eye that processes visual information and sends it to the brain. When the retina detaches, common symptoms in the affected eye include seeing floaters, flashing lights, and/or a dark shadow, as well as sudden blurry vision. The most common type of retinal detachment is rhegmatogenous, which occurs when a tear or hole in the retina lets fluid from the center of the eye get behind it, causing the retina to pull away.
